T0 all 'whom t may concern.'

Be it known that I, CORNELIUS Ross, a citizen of I-Iolland, residing atLos Angeles, in the county of Los Angeles and State of California, haveinvented new and useful Improvements in Extension Tables, of which thefollowing is a specification.

My invention relates more specifically to `a pivoted table leafconstruction for extension tables. p

It is an important object of my invention to provide a foldable tableleaf construction pivotally disposed on the frame of an extension tablebelow the table top, and arranged to be elevated upwardly to fill thespace between the table sections when they are drawn apart to form anextended top.

Another object is to provide a foldable table extension leafconstruction that is extremely simple in construction, easily operatedwhen it is desired to extend a table top, and which is not liable tobecome easily disorganized.

In the accompanying dra- Ying I have illustrated a preferred embodimentof my invention, it being understood, however, that no limitation isnecessarily made to the precise structural details therein exhibited,but various changes, alterations and modifications may be resorted towithin the scope of my invention when desired.

Fig. 1 is a plan view of an extension table in its closed position, thefoldable extension leaf being shown in dotted lines.

Fig. 2 is a plan view of an extension table in an extended position,with the foldable extension leaf in place therein.

Fig. 3 is an enlarged transverse section of an extension table in aclosed position equipped with my foldable extension leaf, taken on line3--3 of Fig. 1.

Fig. 4 is a bottom plan view of an extension table with the tablesections drawn apart, the foldable extension leaf in a folded position.

Fig. 5 is an enlarged longitudinal section of an extension table top,with the foldable extension leaf in position, taken on line 5 5 of Fig.2.

Referring more specifically to the drawings, 6 indicates an extensiontable rectangular in form, consisting of two sections 7, S, eachprovided with a pair of supporting legs 9, 10, and a centrally disposedframe work 11, formed of longitudinally extending side bars 12, 13. Eachpair of ends Iof the side bars are connected by a plurality of shortbars 14, 15, 1.6, suitably secured to the side bars, and s} 3ac`ed.apart to form grooves 17, 13, the oppositely disposed faces of thevarious bars being provided with longitudinally extending tongues 19that engage with grooves 20 formed in the' side faces of slide bars 21,22, 23, 24, a pair of bars being secured to the `under face of Veachtable section.

The above described construction is the form most generally employed'vin extension table construction, and therefore' form no?` part of myinvention, except in combination with my foldabl'e extension` leafIwhichv is attached thereto. Further, it will be perfectly obvious thatthe table top other than rectangular formation.

The foldable extension leaf is preferably formed in two sections 30, 31,rtheir abutting ends being hinged togetherby means of the usual wellknown concealed hinges may be of- 32. Each of the oppositelyj disposedfaces of side bars v12', 13, .areprovided with longitudinally extendingguide grooves 33, 34, the grooves extending between the oppositelydisposed faces of said bars 16 as clearly shown in Fig. 4 of thedrawings. Attached to the under ,face of section 31 of the foldable leafand adjacent its hinged end by means of bearings 35, is a leaf elevatinghinge 36, in this instance formed of stiff wire, the transverselydisposed portion 37 of the hinge 36 is mounted in the bearings 35 andits side arms 38, 39, are bent at right angles thereto and lie parallelto the grooved faces of the side bars. treme ends of the side armspivotally engage slide blocks 40 that are mounted in the grooves 33, 34,formed in the side bars, in order to permit of a forward movement of theleaf during its elevation. Securedto the under face offleaf section 31,at the proper distance from its outer end, is another leaf elevatinghinge 43, similar to hinge 36, its transversely extending portion 44being mounted in bearings 41, and its side arms 45, 46, lying parallelto the grooved faces of the side bars 12, 13, the extreme outer endsengaging bearings 47 secured to the outer side face of one of the endbars 16 substantially mid-way between its upper and lower edges. Sidearms 45,

The exa ltween the table sections.

46, are bent at right angles adjacent their point of attachment to theend bar 16, in order that the side portions will lie parallel to theunder surface of the leaf section when the leaf is swung into positionbe- The upper surface of bars 14, 15, 16, and bars 28, 24, on which theleaf section 81 rests when the leaf is swung into position, are cut awayto form a depression 50 for the accommodation of the side portions 45,46, of the hinge 43 when the leaf is in position between the tablesections.

When the table is in its normal closed position, the sections of theextension leaf are folded upon each other, leaf 31 resting directly uponthe upper edges of the side bars 12, 13, directly below the two sectionsof the table top, thus effectually concealing the. leaf from view, asclearly shown in Fig. 3 of the drawings. YVhen it is desired to extendthe'top of the table the two sec tions are drawn apart (see Fig. 4), theoperator then grasps the end of the leaf section toy which the elevatinghinge 43 is secured and pulls the same toward him, the side arms of eachof the hinges raising the leaf sections to a level with the uppersurface ofthe tops of the table sections, the blocks sliding in thegrooves 83, 34, of the side bars and permitting of a forward movementduring the elevation, stops 51 disposed in the grooves 33, 34, of theside bars limiting the forward movement of the folded leaf sections.After the above opera tion has been completed the upper folded section30 of the leaf is swung on its hinges into position to fill the spacebetween the table section opposite to the space occupied by section 31.rIhe two table sections are then pushed together until their oppositelydisposed edge contacts with the side edges of the leaf sections, thuscompleting the operation of extending the table top.

From the above description it will be apparent that I have provided asimple foldable extension leaf construction, that will be inexpensive toconstruct, and one not easily disarranged.

l/Vhat I claim is:

In combination with an extension table consisting of a pair of sectionsadjustably secured together, of an extension table leaf divided into twohinged sections and normally supported by the table frame below the topsof the table sections, a pair of arms pivotally attached at one of theirends to one of the leaf sections, their free ends being pivotallysecured to the table frame, and a second pai-r of arms pivotallyattached to the last named leaf section, their f ree ends beingpivotally attached to movable pivot blocks, whereby when the tablesections are drawn apart the foldable table leaf may be swung into anelevated position to fill the intervening space between the tablesections.

In witness that I claim the foregoing I have hereunto subscribed my namethis 7th day of June, 1924.

CORNELIUS ROSS.
